We have provided many systems for monitoring the temperature of buried power cables, both in Japan and overseas. We can provide various graphic software for monitoring purposes.
In the Berlin subway, temperature data gathered from newly installed as well as pre-installed communication cables were evaluated and compared to
Conductor temperatures, cable ampacities and emergency ratings are computed in real time (real-time thermal rating – RTTR), enabling operational flexibility and the ability to uprate the cable.
DTSX measures temperature distribution over the length of an optical fiber cable using the fiber itself as the sensing element and it is ideal for temperature monitoring over long distances and wide areas.
High-resolution temperature sensing with Raman optical frequency domain reflectometry (OFDR) using optical communication fiber cables shows great potential as it allows the surveillance of several
